DISK PLOW.

SPECIFICATION forming part of Letters Patent No. 596,390, dated December28, 1897.

Application filed July 7, 1897. serial No. 643,734.. (Model.)

Totll whom, it may concern.- y Be it known that I, OLIVER P. WoLoo'r'r,a citizen of the United States, and a resident of Dallas, in the countyof Dallas and State of enable Others Skilled .in the am to which itappertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification.

My invention relates to disk or revolving plows; and its object is toprovide an improved attachment or cutter therefor which travels inadvance of the disk which undercuts part of the unplowed soil, and thedisk which followscuts the remainder and turlls the ground, leaving thefurrow level, and at the same time the cutter will hold the disk down toits work.

The invention consists, essentially, in the novel construction andcombination of parts hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a perspective View of a diskor revolving plow constructed in accordance with my invention. Fig. 2 isa detail perspective view of the cutter removed.

In the said drawings the reference-numeral l designates the plow-frame,and 2 the axle, provided with a main driving-wheel 8. The opposite endof the frame is provided with an Ainclined axle 4, to which is journaledthe inclined wheel 5, and at the rear is a steering or caster wheel 6. y

The numeral 7 designates the revolving disk, which is set at an angle tothe line of draft, so as to engage with the soil and turn the furrow.

The parts so far described may be of any ordinary or usual construction,and a detailed description thereof and of the other accessorial partswhich form no part of my invention is not necessary.

The numeral Sdesignates my improved cutter, consisting of aforwardly-inclined standard 9, having its lower end turned or bentinwardly at a right angle, forming a horizontal blade lO, the frontofwhich is formed with an inclined cutting edge. The disk 7 isconcavoconvex and is inclined at an angle to the line of draft. Thehorizontal blade travels in front of the concave side of the disk andparallel with the line of draft of the plow. By this construction inoperation the horizontal blade will undercut the soil in advance of thedisk, making a perfectly level cut, and the disk following the bladewill cut and turn the furrow. By this means the disk will be held to itsworkand the furrow will be cut and turn ed more expeditiously than ifthe cutter were dispensed with.

Having thus fully described my invention, what I claim isl. In a rotaryplow, the combination with the furrow cutter and turner, consisting ofthe rotatable c oncavo-convex disk located at an angle to the line ofdraft, of the horizontal cutter located in front of said disk, oppositethe concave surface thereof and provided with a forwardly extendingstandard, substantially as described.

2. In a plow, the combination with the concavo-convex disk, located atan angle to the line of draft, of the downwardly-extending bar havingits lower end bent or turned inwardly forming a flat horizontal blade,having its front end formed with an inclined cutting edge and whichtravels in advance of the concave side of the disk and in a lineparallel with the line of draft, substantially as described.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of 'two witnesses.

OLIVER P. WOLCOTT.
